My invention relates to improvements in windows; and the object of my improvements is to provide a specially constructed, spring metal weather strip placed in the channel of a common double hung window frame, to prevent the sash from rattling in the frame, a much needed advantage in this type of window and to hold the slide bars in the channel when the sash is removed.

Flgure l is a front elevation, from inside with the sashes closed.

Figure 2 is a vertical section, with the sashes closed.

Figure 3 is a horizontal cross section of the window.

Figure 4 is a vertical cross section showing the sash locked open and also showing the sash reversed into the room, by broken lines.

Figure 5 is a view of the hinge.

Figure 6 is a cross section of a jamb showing the relation of the improved metal weather strip bars to the jamb and sash.

Figure 7 is a cross section of a jamb and sash showing the latch.

Figure 8 is a detailed section of the safety rest.

Figure 9 is an isometric projection of the slide bar.

Figure 10 is an isometric projection of the stile strip.

Figure 11 is a view of the under side of the bar stop.

Similar numerals refer to similar parts throughout the several views as follows: ii] is the jamb; H is the head jainb; i2 is the sill; i3 is the blind stop; I 4 is the parting stop; 55 is the window stop; i6 is the upper sash stile; ll is the lower sash stile; I8 is the pulley; i9 is the chain; 2% is the weight; 25 is a V type weather strip; 22 is a metal weather strip bar free to move in the channel of the frame, this being formed with a lip 22 23 is a metal weather strip stile bar screwed to a stile; 24 is an opening in the slide bar channel which receives a spring weather strip causing the bar to be held in place; 25 is the spring metal weather strip constituting one of the features of this invention. The lip 22 extends between the spring 25 and the bottom of the channel of the frame; 21 is the pivot for hinge; 28 is a hole in the slide bar to receive the pivot; 29 is a bar stop; 35] is a sash latch; 3! is an orifice to receive the latch in the window stop; 32 is a safety device rest to hold the stile when the sash is in tilted position; 33 is an orifice to receive the latch in the metal weather strip bar; 34 is an orifice in the bar stop to receive the latch 30;

a few inches, then tilt the upper sash into the 10 room in the same manner as the lower sash. Place latches 39 in the orifices 36 which are located in the stationary bar stop 2Q. Thus the window is locked yet both sashes may be used for indirect ventilation and no one can enter the win- 1 (low from outside for the latches 33 must fh'st be released from inside in order to have the sash move.

The reversal of the sash into the room is done in th s manner. Raise the lower sash until it is stopped by the bar stop 29, release the latches 30 as for indirect ventilation and pull the lower sash into the room until it rests on the safety bumper 32. To reverse the upper sash first have the lower sash resting on the safety bumper 32, then bring the upper sash into the room as in the process of indirect ventilation. Let the upper sash swing clear until it rests upon the lower sash. It can now be observed that there is no undue strain on the hinge pin 27 as the sash have only 30 their weight on the hinge 2i and are not acting as a lever to bend or loosen the pin. To replace the sash reverse these operations.

Removing the sash may easily and quickly be done without the use of tools by first reversing the sash, then by holding either sash in a horizontal position, twist the sash so that one stile H6 or ii is lowered. The hinge pin 27 automatically slips free from the hole in slide bar 28. The hinge pin 27 has a ball shaped end so as to allow perfect 40 case in engaging and disengaging, yet it is long and will not allow the sash to fall out when reversed but must go through the process described in order to remove the sash. To replace the sash reverse these operations.

The bar stop 29 allows the lower sash to rise only as far as the stop 29. When the slide bar 22 has been stopped in this position the lower sash is ready for disengagement and holds the bars 22 from sliding upwards when the sash has 0 been reversed into the room. The bar stop 29 also gives the slide bars 22 the proper location for the returning of the sash. The bar stop 29 is stationary, has no movable parts, hence cannot 5 deteriorate or get out of order.

The safety rest 32 prevents the raising of the lower sash when the sash has been tilted inwardly for ventilation yet not locked in that position. The sash must first be closed before raising, as the projection screw 35 fits in the orifice 36 and must first be released before the sash can be raised. Another orifice serves'either as a safety catch or may be used to tilt the sash at a greater angle for indirect ventilation, the sash being slightly raised. An appropriate height of the safety rest 32 is determined at the time of manufacture of hardware which height varies with the size of the windows. The lower sash rests upon the highest point of the safety rest 32 when the sash has been reversed into the room, thus keeping the lower sash from marring the finish on the stool of the window.

The spring metal weather strip 25 of novel construction is particularly important as it seals the slide bar 22 to the frame channel making a wind-tight joint and acts as a guide for the slide bars 22. This spring weather strip extends lengthwise of the bottom of the channel in the frame and is secured thereto and extends into the recess in the slide and the lip 22 on the slide hooks under the spring strip. This spring strip 25 presses against the bottom of the recess in the slide and tends to press the slide outward against the sash, and the lip 22 extends between the spring strip and the bottom of the channel and prevents displacement of the slide out of the channel. Thus, the weather strip 25 holds the slide bars 22 in position when the sash. has been removed and also in the correct position for the replacement of the sash. The C bend allows the slide bar 22 more freedom and will allow the sash to be moved freely even if the sash was constructed with more than an adequate amount of clearance, between the sash and the frame which is a common construction fault. The G bend has two points touching the metal slide bar 22. One point pushes the slide bar 22 away from the channel towards the sash, aiding in the engagement of the vertical V joint between the slide bar 22 and the stile bar 23 when the sash is being returned. The other point pushes the slide bar 22 towards the blind stop 13 or the parting stop l4 against the outside of the window frame, eliminating rattles. In this manner the channel may be considerably wider than necessary to allow the slide bar to run freely, yet there will be no rattling caused by the wind as the slide bar 22 is held rigid between the spring weather strip 25 and the frame.

The interlocking V joint 2! is used to aid in the return of the sash from reversing, the tip having been engaged, the entire vertical strip is obliged to engage from the nature of the joint. It also makes a weather tight connection between the sash and the slide bars 22.

The sash slide up or down as in the common double hung windows, yet the benefits of my hardware of novel construction enable one to easily change at a small cost the common double hung window into a window having all the desirable features previously described.

There are two sizes of stile bars 22, the upper being slightly thicker than the lower causing the upper sash to be narrower than the lower sash, allowing the upper sash to tilt inwardly, passing stile bars 22 of the lower sash. My improved window by use of these two sizes of stile bars as shown in Figure 6 is adaptable to the commonly used frame because of my narrow weather strip on stile bars 22.

What I claim as my invention is:

In a window, the combination with a window frame having stops forming opposing guide channels, a sash having slides at the edge of its stiles, said slides slidably fitting the channels, and the sash being pivoted to the slides and having releasable means for normally holding the sash from pivotal movement, the slide being form-ed with a lengthwise recess in its face opposed to the bottom of the channel, and being also formed with a lip extending lengthwise thereof extending into the recess, a spring consisting of a strip extending lengthwise of the bottom of the channel and secured thereto and extending in the recess, the spring pressing against the bottom of the recess in the slide and tending to press theslide outward against the sash, and said lip extending between the spring and the bottom of the channel.
